Hello,
I am very glad that you like the designs so far.
This logo is simple and very memorable. It can be used as only a logo mark and still will be able to recognize it and also it can be used from very small size like for a pencil till big as for billboard. One logo need to be able to be used on different kind of print materials.
I have submitted couple of different executions, in #119 I made the icon more stylizes so now it look like a house representing that you work with real estate.
Hope you like it and if you have any ideas or suggestions please feel free to let me know
